• Handle API onboarding and implementation support for corporate clients using ICICI Bank's Host-to-Host payment integration
solutions.
• Perform end-to-end API testing for payment and collection workflows, including authentication, encryption, request/response validation,
and transaction status verification.
• Validate HMAC/OAuth-based authentication, token handling, API payloads, headers, error responses, and integration scenarios using
Postman.
• Support client technical teams during API integration, debugging connectivity issues, transaction failures, and request validation errors.
• Coordinate with internal product, operations, and technical teams to resolve integration issues and ensure smooth corporate client
onboarding.
• Prepare API documentation, integration notes, testing observations, and client FAQ material for implementation support.

• Developed a Python-based REST API automation framework for DDRS/Recykal workflows with HMAC authentication, token
management, and CSV-driven test execution, reducing manual testing effort by 70%.
• Performed API testing, regression testing, and integration testing across multiple backend workflows using Postman and Python
scripts.
• Validated YOLOv5/YOLOv8 object detection models deployed on Jetson Nano, including inference testing, confidence threshold
tuning, and accuracy validation using Precision, Recall, and F1-Score.
• Developed automation scripts for fabrication quality checks of RVM machine components, including touchscreen, QR scanner, camera,
AI item detection, sensors, audio, and LED indicators.
• Executed performance, stress, and load testing using Apache JMeter and analyzed network behavior using Wireshark for latency,
bandwidth, and packet loss.
• Participated in regression testing, UAT testing, defect reporting, and test result documentation for software and hardware-integrated
systems.

• Designed and executed 300+ test cases for web and mobile applications, improving defect detection and test coverage.
• Performed API testing across 50+ REST endpoints using Postman, covering HTTP methods, status codes, request/response
validation, schema validation, authentication, and negative test scenarios.
• Conducted integration testing for CRM platform workflows, validating communication between frontend, backend services, reports, and
integration modules.
• Performed database testing using SQL and MySQL Workbench to verify backend data accuracy, data flow, and table-level validation.
• Tested Android mobile applications for UI/UX, navigation flow, responsiveness, offline behavior, and cross-device compatibility.
• Monitored AWS CloudWatch logs to debug API issues and support faster defect identification and resolution.
